Jakarta, Indonesia (CNN) -- Two bodies were found Tuesday at the scene of a tunnel collapse at an underground mine training facility in Indonesia, the mining company said.
The Indonesian government said a tunnel roof collapsed after a landslide.
More than 30 people remain trapped. Four people were rescued and three people escaped, PT Freeport Indonesia said.
"We extend our heartfelt condolences to the families of the deceased," said PT Freeport Indonesia President Rozik B. Soetjipto.
The area of the incident is located outside of mining areas, about 500 meters from the entrance of the Big Gossan Mine.
Freeport Indonesia mines copper, gold and silver.
